You defined ID as const.

Also your <pre> tags are being ignored, have a look at the setting of the Treat my content as plain text, not as HTML checkbox, at the bottom of this page and/or in your settings page.

Hi everyone
I have three questions
1.why do I need to use of TEXT macro in my codes and if I remove it compiler shows error
2.why CreateProcess cant open test.txt while second parameter is command line and I have to write full path ("c:\\notepad.exe c:\\1.txt")
3.Do I need to use of WaitForSingleObject
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof (STARTUPINFO);
GetStartupInfo (&si);
si.dwFlags = STARTF_USESHOWWINDOW |STARTF_TITLEISAPPID ;
si.wShowWindow = SW_SHOWMAXIMIZED;
si.lpTitle=TEXT("Test");
if(CreateProcess(TEXT("c:\\notepad.exe"),TEXT("c:\\test.txt"),NULL,
NULL,FALSE,NULL,NULL,NULL,&si,&pi))
{
//WaitForSingleObject(pi.hProcess, INFINITE);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}

Thanks

Do you understand the difference between absolute vs. relative paths?

Only if you need to wait.

exporting data from C++ to C

Hi I have to program, one is in c++ I have compiled with VStudio 2010, and one in c compiled in gcc.

In c program, I need data which come from c++.
how to export data from c++ to C? does any one have the sample code for this one?

thankyou

Data is data, it has nothing to do with what language is used to process it. Please try and explain your problem in more detail.

I have a program in C++ compile with Visual Studio 2010. This program is to get data from joystick, this joystick will control robot in server pc.
in this client PC I have udp client server in C compile with gcc.

I need to pass data from joystick program to udp client program.

How can I do that? data is in char format, and input udp have the same format.

are there any source code example to do that?

Richard MacCutchan15-Dec-12 20:59

Make a socket connection and send the data, suitably formatted, to your client. I don't understand what the problem is here, transferring data between clients and servers is how the entire world is run these days.

I have udp server client connection it is in C program, but the problem is, that my joystick program in client is in C++, I want to pass C++ data to client C program.

thank you

There is no such thing as "C++ data", data is data, it's just a series of bytes. I cannot see how you are able to write C and C++ code and, apparently, understand UDP client/server, and yet do not understand this basic concept.

You need to read up on Interprocess Communications... and choose one that fits what you need most appropriately according to whether you expect the programs to be on the same machine, speed, reliability, platform dependence (or independence).

Hi all,

Can any one tell me How to overlay text over a video available, using Linux Commands.

I have tried with ffmepg tool, But I can't able to make it possible.

The Command I used was,

ffmpeg -i Input.avi drawtext="fontfile=/usr/share/fonts/truetype/freefont/FreeSans.ttf:text=HelloWorld:fontcolor=red@1.0:fontsize=70:x=00: y=40" -y Output.avi

An Error Message i got:

Unable to find a suitable output format for 'drawtext=fontfile=/usr/share/fonts/truetype/freefont/FreeSans.ttf:text=HelloWorld:fontcolor=red@1.0:fontsize=70:x=00: y=40'

Please let me know, How to work it out or some other Linux tool to overlay a text over Video.

Expecting for the best reply soon

Thanks & Regards

Looking at the documentation xlSheetVisible property

Assembly: Microsoft.Office.Tools.Excel (in microsoft.office.tools.excel.dll)

does this mean this property is exposed in excel.dll if so I only have the executable

thanks

Richard MacCutchan11-Dec-12 11:25

Yes, and you already showed that information in your original question; it is part of the Office interop. However, you need Microsoft Office installed on your system in order to access it. What exactly are you trying to do, and is this really a C++ question?

Then you should have the required DLL's also. Have a look here[^] for some suggestions.

VC++6.0 menu limit?

Hi ALL!
VC++6.0, XP SP3, MFC Dialog-based App.
Adding a next item to the menu I've suddenly got a message "Out of memory. Unable to complete command". After restart it's impossible to load project clicking .DSW file: workspace stays empty, no files loaded.

Killing of the .CLW solves the problem for an one session. After I restart project, it again doesn't work, need delete .CLW again.

Now, I cannot add a menu item. Currently there are about 1000 items in the menu. I have a bad suspicion that may be there is a LIMIT for the wizard when it adds a menu item?

Please, any ideas how to add items?
